I just want to know how did you implement theform action="<?php the_permalink(); ?>" ?
I just want to change it's action and redirect it to a thank you page, but when I tried it I failed. I have posted this problem to various forum sites but I got no answers. I hope someone here can help me.

People will typically not bump into this here, other people looking for solutions to issues and/or feature requests of the "bbPress Moderation" plugin will look to their support forums for this.

As to the issue "that the author has no update anymore" that may be the case, but if you don't actually post on the "bbPress Moderation" support forums neither the plugin owner or other users of the plugin will know about these issues.

I suggest any future (and possibly your previous posts) you post on their support forums before moderators start removing your posts.
